Abstract:

Currently, there are no national standards for color limits in pulp and paper mill wastewaters effluents. In some cases, there are regional or State stream standards based on the receiving waters. Decolorization of this industry wastewater is getting higher concerns due to possible regulations to the color of the discharge effluents. The sustainability of color removal and the degree and rate of decolorization was tested using anaerobic sequential batch reactors. The reactors were prepared by combining anaerobic compost and effluents with dissimilar characteristics. In addition, experiments were conducted to study the color reversion and to confirm that color reduction was due to anaerobic biodegradation. Results of these experiments shows that color reduction in these reactors varied from 75% for an effluent with initial color of 89,500 PCU to 88% for an effluent of 3,900 PCU. Reaction constants for the effluents studied varied from 0.0083 to 0.0164/hr. Aeration of the effluents showed little color reversion which indicates that color was degraded under anaerobic conditions.
